【国外标准】 Standard Guide for the Use of Geocells in Geotechnical and Roadway Projects

5.1 This guide covers applications, support mechanisms, and design principles associated with geocells to help designers and engineers determine when and how to appropriately use this technology.5.2 A better understanding of the key design principles, material properties, mechanisms of improvement, and methodologies will help engineers and owners interested in using geocells understand the most efficient and appropriate ways to utilize this type of ground improvement for a variety of geotechnical-related applications.5.3 This guide does not preclude the judgment and practice of those competent in geotechnical design.1.1 This guide is intended to cover basic considerations for the use of geocells in various geotechnical and roadway projects to bring a unified understanding of efficient and appropriate ways to utilize this type of ground improvement technology for a variety of geotechnical-related applications, including but not limited to: load support for pavements, subgrade improvement, slope stability, retaining walls, earth retention, and slope and channel protection. Engineers and owners interested in using this manufactured product can refer to the information in this guide to learn about key design principles, properties, mechanisms, and methodologies for applicable geotechnical applications. Geotechnical designs that incorporate geocells should take into consideration the specific attributes of each product. The engineer is encouraged to utilize design methodologies based on reliable test results and research.1.2 This guide offers a collection of information and does not recommend a course of action. This guide cannot replace education or experience, and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances.1.3 This guide is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this guide be applied without consideration of a project’s many unique aspects.1.4 The word “standard” in the title of this guide means only that this guide has been approved through the ASTM International consensus process.1.5 The values given in SI units are to be regarded as standard. Values in parentheses are for information only.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
